3M™ EMI Absorber AB8000 Series is a high-temperature magnetic near-field EMI absorber material for electronic applications from 300 MHz to 4 GHz. The composite material features a silicone carrier resin for stable solder reflow and strong attachment to FPCs along with magnetic fillers to suppress near-field EMI noise inside and around electronic devices and assemblies. The 3M™ EMI Absorber AB8000 series also functions as a magnetic shielding material for reducing EMI transmissions or reflections in the EM field.
